Usage of FormManager in "advanced" theme

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/97150ae226548689#

We've developed FormManager javascript class, that can be used to create forms, that are validated on the fly using ajax.
However it's only used in modern-store theme that isn't even released.

I'm proposing to use it also in "advanced" theme, that is widely used.
